Abstract
With increased consumption of minimally processed ready-to-eat foods the potential for exposure to Listeria monocytogenes has increased. Thus, there is a need to maintain a balance between food convenience and safety. L. monocytogenes is not a homogenous species; certain strains are more resilient to stressful conditions while others are potentially more virulent. To understand the basis of these differences we are applying proteomics to determine the molecular mechanism of adaptations of L. monocytogenes in food-relevant environments. The goal is to define how this species grows, behaves and survives thus allowing us to fine tune food safety risk management, especially when developing new minimal food processes or considering introduction of unpasteurised food such as raw milk cheeses.
